The water stains on the surface of the light-transmitting plate are scraped off by the wiper assembly, thereby cleaning the light-transmitting plate to prevent excessive dust on the surface of the light-transmitting plate, which would result in poor viewing effect of the advertisement.

[0009] Preferably, the wiper assembly includes a fixed block, the inner wall of the fixed block is slidably connected with an arc slide plate, one side of the arc slide plate is fixedly connected with a connecting plate, the other side of the arc slide plate is slidably connected with a movable rod, the top end of the movable rod is slidably connected with a push rod, the outer side of the push rod is fixedly connected with a tension spring, the top end of the tension spring is fixedly connected with a fixed plate, the top of the fixed plate is fixedly connected with a telescopic tube, the top end of the telescopic tube is fixedly connected with a mounting plate, the mounting plate is rotatably connected with a clamping plate on a side away from the telescopic tube, and the outer wall of the clamping plate is clamped with the wiper plate. The staff simultaneously holds the pressing plate and the connecting plate so that the connecting plate approaches the pressing plate. At this time, the arc slide plate slides along the inner wall of the fixed block and drives the push rod to move downward through the movable rod. At this time, the tension spring is stretched by force, and the telescopic tube contracts with the movement of the push rod, so that the mounting plate moves downward.

[0010] Preferably, the top of the fixed block is fixedly connected to the bottom of the metal water storage cylinder, the outer wall of the connecting plate is slidably connected to the outer wall of the metal water storage cylinder, and the outer wall of the metal water storage cylinder is fixedly connected to the outer wall of the fixed plate. When the mounting plate moves downward, the wiper plate is deflected relative to the fixed plate under the limiting action of the clamping plate and maintains contact with the surface of the light-transmitting plate, thereby allowing the water stains on the surface of the light-transmitting plate to be scraped off by the wiper plate.

[0011] Preferably, the outer wall of the fixed plate is rotatably connected to the inner wall of the wiper plate, the inner wall of the fixed plate is slidably connected to the outer wall of the push rod, the top of the push rod is fixedly connected to the top of the inner cavity of the telescopic tube, the outer wall of the wiper plate is in contact with the outer wall of the light-transmitting plate, and the wiper plate is driven to reset by arranging a tension spring.

[0013] Preferably, the inner wall of the water tank is slidably connected to the outer wall of the slide rod, the outer wall of the limit block is plugged into the inner wall of the water tank through a limit hole, and the limit hole is opened in the wall of the water tank.

During the rotation process, the rotating block can pull the rectangular positioning plate to slide in the sliding sleeve through the U-shaped connecting rod, so that the rectangular positioning plate is separated from the inner wall of the limiting plate. At this time, the water tank can be removed.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention provides a magnetic block so that visitors can view the advertisement content through the light-transmitting plate in the protective device. When the surface of the light-transmitting plate is dirty, the surface of the light-transmitting plate can be cleaned by pulling down the cleaning device. The cleaning device is adsorbed by the magnetic block so that the cleaning device can be fixed on the top of the protective frame when not in use, which not only saves space but also avoids possible damage caused by random placement of the cleaning device.

[0017] 2. The present invention sets a protective device and a cleaning device to cooperate with each other. In the process of pulling the cleaning device downward, the sliding plate in the cleaning device slides downward along the inner wall of the protective frame, and forces the spiral rod to rotate in the process of sliding downward. At this time, the fan blades at the bottom of the spiral rod rotate, and blow the air in the base into the split jet pipe through the air guide pipe. Finally, the air is blown out from the split jet pipe, which can blow off the dust attached to the inner wall of the curtain wall. In this way, the curtain wall can be cleaned while cleaning the light-transmitting plate, which greatly improves the cleaning efficiency and cleaning effect.

[0018] 3. The present invention provides a cleaning device, adds clean water into the metal water storage cylinder through the water inlet pipe, and then blows air into the metal water storage cylinder through the air pump to increase the pressure in the metal water storage cylinder, so that the clean water can be sprayed onto the surface of the light-transmitting plate through the nozzle, and at the same time, the water stains on the surface of the light-transmitting plate are scraped off by the wiper assembly, thereby cleaning the light-transmitting plate to prevent dust from gathering on the surface of the light-transmitting plate, which would lead to a poor viewing effect of the advertisement, thereby ensuring a clear display of the advertisement and not affecting the customer's viewing experience of the advertisement due to the dirtiness of the light-transmitting plate.

[0019] 4. The present invention sets a wiper assembly. The staff holds the pressure plate and the connecting plate tightly at the same time, so that the connecting plate moves closer to the pressure plate. At this time, the arc-shaped slide slides along the inner wall of the fixed block and drives the top rod to move downward through the movable rod. At this time, the telescopic tube shrinks with the movement of the top rod, so that the mounting plate moves downward. At this time, under the restriction of the clamping plate, the wiper plate deflects relative to the fixed plate and keeps in contact with the surface of the light-transmitting plate, so that the water stains on the surface of the light-transmitting plate can be scraped off by the wiper plate.

[0020] 5. The present invention sets a water hanging component and drives the wiper to reset by stretching the spring. When the cleaning device runs to the lower dead point, the staff loosens the connecting plate and drives the cleaning device to reset by lifting the pressure plate. At this time, under the elastic force of the stretching spring, the wiper is reset and separated from the surface of the light-transmitting plate, which can prevent the light-transmitting plate from bringing up the scraped water stains when the cleaning device is reset, resulting in a poor cleaning effect.

[0021] 6. The present invention sets a collecting component, and the water stains scraped by the wiper blade eventually flow into the water storage tank in the collecting component through the leakage groove, which can prevent sewage from accumulating at the bottom of the protective frame. When it is necessary to clean the sewage in the water storage tank, the turntable is rotated to make the rotating block rotate with the slide rod. During the rotation process, the rotating block can pull the rectangular positioning plate to slide in the sliding sleeve through the U-shaped connecting rod, so that the rectangular positioning plate is separated from the inner wall of the limit plate. At this time, the water storage tank can be removed and the sewage can be cleaned. The operation process is simple and easy to use.

[0022] 7. The present invention sets a collecting component. When the leakage tank is blocked by sewage, the turntable is rotated to align the limit block with the limit hole to hold the water tank, and then the slide bar is pulled downward by the turntable, so that the slide bar drives the sealing plate to slide downward along the inner wall of the water tank. At this time, the water tank is in a negative pressure state. Under the action of atmospheric pressure, the sewage above the leakage tank can be sucked into the water tank.

[0023] 8. The present invention provides a collecting assembly. If the water storage tank is full of sewage and the sewage cannot flow into the water storage tank through the leakage groove, the storage space of the water storage tank can be increased by pulling the slide bar and the sealing plate downward through the turntable, so that the sewage accumulated at the bottom of the protective frame can flow smoothly into the water storage tank. At the same time, the sealing plate can also isolate the sewage to prevent the sewage from flowing downward and out of the bottom of the water storage tank to corrode other components in the collecting assembly.

[0045] When the cleaning device 3 is pulled downward, the sliding plate 31 in the cleaning device 3 slides downward along the inner wall of the protective frame 11, and forces the spiral rod 14 to rotate during the downward sliding process. At this time, the fan blade 15 at the bottom of the spiral rod 14 rotates, and blows the air in the base 13 into the split jet pipe 10 through the air guide pipe 16. Finally, the air is blown out from the split jet pipe 10, and the dust attached to the inner wall of the curtain wall 2 can be blown off, so that the curtain wall 2 can be cleaned while cleaning the light-transmitting plate 12;

[0046] When the cleaning device 3 is in use, clean water is added into the metal water storage cylinder 32 through the water inlet pipe 34, and then the air pump 33 is used to blow air into the metal water storage cylinder 32 to increase the pressure in the metal water storage cylinder 32, so that the clean water can be sprayed onto the surface of the light-transmitting plate 12 through the nozzle 37, and at the same time, the water stains on the surface of the light-transmitting plate 12 are scraped off by the wiper assembly 36, thereby cleaning the light-transmitting plate 12 to prevent the surface of the light-transmitting plate 12 from being dusty, which may cause poor viewing effect of advertisements;

[0047] During this process, the staff simultaneously holds the pressing plate 35 and the connecting plate 362 tightly, so that the connecting plate 362 moves closer to the pressing plate 35. At this time, the arc-shaped slide plate 363 slides along the inner wall of the fixed block 361, and drives the top rod 365 to move downward through the movable rod 364. At this time, the tension spring 366 is stretched by force, and the telescopic tube 368 shrinks with the movement of the top rod 365, so that the mounting plate 369 moves downward. At this time, under the limiting effect of the clamping plate 370, the wiper plate 371 deflects relative to the fixed plate 367 and keeps in contact with the surface of the light-transmitting plate 12, so that the water stains on the surface of the light-transmitting plate 12 can be scraped off by the wiper plate 371.

[0048] The stretch spring 366 is provided to drive the wiper plate 371 to reset. When the cleaning device 3 runs to the lower dead point, the staff loosens the connecting plate 362 and drives the cleaning device 3 to reset by lifting the pressure plate 35. At this time, under the elastic force of the stretch spring 366, the wiper plate 371 is reset and separated from the surface of the light-transmitting plate 12, so that the light-transmitting plate 12 can prevent the light-transmitting plate 12 from carrying up the scraped water stains when the cleaning device 3 is reset, resulting in a poor cleaning effect.

[0049] The water stains scraped off by the wiper blade 371 eventually flow into the water storage tank 131 in the collection assembly 18 through the leakage groove 17, which can prevent the sewage from accumulating at the bottom of the protective frame 11. When it is necessary to clean the sewage in the water storage tank 131, the rotating disk 134 is rotated to make the slide bar 133 drive the limit block 135 to rotate together. At this time, the rotating block 136 rotates together with the slide bar 133. During the rotation process, the rotating block 136 can pull the rectangular positioning plate 139 to slide in the sliding sleeve 130 through the U-shaped connecting rod 138, so that the rectangular positioning plate 139 is separated from the inner wall of the limit plate 19. At this time, the water storage tank 131 can be removed and the sewage can be cleaned. The operation process is simple and easy to use.

[0050] When the sewage blocks the leakage tank 17, the rotating disk 134 is rotated to align the limit block 135 with the limit hole 137 to hold the water tank 131, and then the sliding rod 133 is pulled downward by the rotating disk 134, so that the sliding rod 133 drives the sealing plate 132 to slide downward along the inner wall of the water tank 131. At this time, the water tank 131 is in a negative pressure state. Under the action of atmospheric pressure, the sewage above the leakage tank 17 can be sucked into the water tank 131;

[0051] Among them, if the water tank 131 is full of sewage, causing the sewage to be unable to flow into the water tank 131 through the leakage groove 17, the slide rod 133 and the sealing plate 132 can be pulled downward by the turntable 134 to increase the storage space of the water tank 131, so that the sewage accumulated at the bottom of the protective frame 11 can flow smoothly into the water tank 131. At the same time, the sealing plate 132 can also isolate the sewage to prevent the sewage from flowing downward and out of the bottom of the water tank 131 to corrode other components in the collection assembly 18.

When in use, the advertising image is projected onto the inner wall of the curtain wall (2) through the projector (5), and then the advertising sound is played through the speaker (4), so that visitors can see the advertising content through the light-transmitting plate (12) in the protective device (1). When the surface of the light-transmitting plate (12) is dirty, the surface of the light-transmitting plate (12) can be cleaned by pulling down the cleaning device (3), wherein the cleaning device (3) is adsorbed by a magnetic suction block (6), so that the cleaning device (3) can be fixed on the top of the protective frame (11) when not in use; When the cleaning device (3) is pulled downward, the sliding plate (31) in the cleaning device (3) slides downward along the inner wall of the protective frame (11), and forces the spiral rod (14) to rotate during the downward sliding process. At this time, the fan blade (15) at the bottom of the spiral rod (14) rotates and blows the air in the base (13) into the split jet pipe (10) through the air guide pipe 16. Finally, the air is blown out from the split jet pipe (10) to blow off the dust attached to the inner wall of the curtain wall (2), thereby cleaning the curtain wall (2) while cleaning the light-transmitting plate (12); When the cleaning device (3) is in use, clean water is added to the metal water storage cylinder (32) through the water inlet pipe (34), and then air is blown into the metal water storage cylinder (32) through the air pump (33) to increase the pressure in the metal water storage cylinder (32), so that the clean water can be sprayed onto the surface of the light-transmitting plate (12) through the nozzle (37), and at the same time, the water stains on the surface of the light-transmitting plate (12) are scraped off through the wiper assembly (36), thereby cleaning the light-transmitting plate (12) to prevent excessive dust on the surface of the light-transmitting plate (12), which would result in poor viewing effect of the advertisement; During this process, the staff simultaneously holds the pressing plate (35) and the connecting plate (362) tightly, so that the connecting plate (362) moves closer to the pressing plate (35). At this time, the arc-shaped slide plate (363) slides along the inner wall of the fixed block (361) and drives the push rod (365) to move downward through the movable rod (364). At this time, the tension spring (366) is stretched by force, and the telescopic tube (368) contracts with the movement of the push rod (365), so that the mounting plate (369) moves downward. At this time, under the limiting action of the clamping plate (370), the wiper plate (371) deflects relative to the fixed plate (367) and maintains contact with the surface of the light-transmitting plate (12), so that the water stains on the surface of the light-transmitting plate (12) can be scraped off by the wiper plate (371); A tension spring (366) is provided to drive the wiper plate (371) to reset. When the cleaning device (3) runs to the lower dead point, the staff loosens the connecting plate (362) and drives the cleaning device (3) to reset by lifting the pressure plate (35). At this time, under the elastic force of the tension spring (366), the wiper plate (371) is reset and separated from the surface of the light-transmitting plate (12), so that when the cleaning device (3) is reset, the light-transmitting plate (12) is prevented from carrying the scraped water stains, resulting in a poor cleaning effect. The water stains scraped off by the wiper blade (371) eventually flow into the water storage tank (131) in the collection assembly (18) through the liquid leakage groove (17), thereby preventing sewage from accumulating at the bottom of the protective frame (11). When it is necessary to clean the sewage in the water storage tank (131), the rotating disk (134) is rotated so that the slide bar (133) drives the limit block (135) to rotate together. At this time, the rotating block (136) rotates together with the slide bar (133). During the rotation process, the rotating block (136) can pull the rectangular positioning plate (139) to slide in the sliding sleeve (130) through the U-shaped connecting rod (138), so that the rectangular positioning plate (139) is separated from the inner wall of the limit plate (19). At this time, the water storage tank (131) can be removed and the sewage can be cleaned. The operation process is simple and easy to use. When the sewage blocks the leakage tank (17), the rotating disk (134) is rotated to align the limit block (135) with the limit hole (137) to hold the water storage tank (131), and then the sliding rod (133) is pulled downward by the rotating disk (134), so that the sliding rod (133) drives the sealing plate (132) to slide downward along the inner wall of the water storage tank (131). At this time, the water storage tank (131) is in a negative pressure state. Under the action of atmospheric pressure, the sewage above the leakage tank (17) can be sucked into the water storage tank (131); If the water storage tank (131) is full of sewage, so that the sewage cannot flow into the water storage tank (131) through the leakage tank (17), the storage space of the water storage tank (131) can be increased by pulling the slide bar (133) and the sealing plate (132) downwards through the rotating disk (134), so that the sewage accumulated at the bottom of the protective frame (11) can flow smoothly into the water storage tank (131). At the same time, the sealing plate (132) can also isolate the sewage, preventing the sewage from flowing downwards and out of the bottom of the water storage tank (131) to corrode other components in the collecting assembly (18).
